Forms Recognition

Previous  Top  Next

Before to recognize forms you have to create an application definition file using the Application Designer package, saving the result as .rfd file: please refer to the specific application documentation to get more informations.

1.

Open the recognition fields file (.rfd) by using the Open command from File menu.

2.

If in the definition of the application has been specified an input images directory, it will be asked if process the images contained into that directory. Otherwise insert files to be processed using the Acquire command, the Acquire and Append command or the Add command from Images menu.

3.

If you want to process just a form, select it and use the Process command from Images menu; if you want to start the recognition of the whole list it needs to use the Process All command.

After starting the recognition there are 3 different phases:

1. Reading phase

It is done automatically: according to the settings selected during the definition of the application, are perofrmed the image processing operation and the different recognition engines are used to transform the images into data. The reading phase gives a percentage of confidence to every character and field recognized. During the recognition it is possible to see the log of what it is happening as well as it is possible to see the point of job in the unit Progress e Log.

2. Verify and Correction phase

This phase requires user presence. If the EBV was enabled then all character having a confidence under the specified threshold are displayed so that the user can verify and correct them in Character Check section: the visualization is by homogenous classes so that is easy for an operator to identify the bad recognized chapes looking a group of similar chapes. Next, alle the fields having a percentage under the predefined threshold, are displayed in the Fields correction section: the user can see both the read data and the original image and can correct bad data. If the text-to-speech option is enabled, then the computer read the recognized data and the operator have just to check the image, increasing the speed and reducing the error rate.

3. Output phase

This phase is automated like the others and it consists in transferring right data into the file or into the database indicated during the application definition phase.

After the processing is checked the box on the left side of each file in the list. If in recognition phase some error occurred or if in correction phase some form was marked as not readable by the user the check is not present so its easy to manage exceptions.

The recognition of forms in Workgroup Reader version is executed using the Recognition Station.
